Objectives: Sarcopenia is recognized as a major public health concern because of its association with several adverse health events. Beta-hydroxy-beta-methylbutyrate (HMB) supplementation reportedly delays the loss of muscle mass and function; however, the effect of HMB on sarcopenia remains inconclusive. We aimed to evaluate the impact of HMB intervention on muscle strength, physical performance, body compositions, and inflammatory factors in older adults with sarcopenia. Design: Randomized, double-blind, placebo-controlled trial. Setting and Participants: This study included subjects aged ≥60 years with sarcopenia which were assigned to the HMB group (HMBG, n=18) and the placebo group (PG, n=16). Intervention: The HMBG and PG were supplied with HMB and placebo products twice daily for 12 weeks, and both received resistance exercise training twice a week in 12 weeks. Measurements: Hand grip strength was selected as the primary outcome; gait speed, five-time chair stand test, body composition and inflammatory indicators were selected as the secondary outcomes. The differences in changes from baseline between the two groups were analyzed using the analysis of covariance(ANCOVA). Results: After the 12-week intervention, the HMBG demonstrated significantly greater improvements in handgrip strength (4.61(95%CI:2.93,6.28) kg, P<0.001), gait speed (0.11(95%CI:0.02,0.20)m/s, P=0.014), five-time chair stand test (−3.65 (95%CI:−5.72, −1.58)s, P=0.001), muscle quality (2.47(95%CI:1.15,3.80),kg·kg−1 P=0.001) and tumor necrosis factorlike weak inducer of apoptosis (−15.23(95%CI:−29.80,−0.66)pmol/mL, P=0.041) compared with the PG; no significant differences in skeletal muscle mass, skeletal muscle index, and other body composition parameters were found between the two groups. Conclusion: In older adults with sarcopenia, HMB significantly enhance the effect of resistance exercise training on muscle strength, physical performance, muscle quality, and reduced inflammatory factors. Therefore, HMB supplementation could be an effective treatment for sarcorpenia. The trial protocol was registered at http://www.chictr.org.cn/showproj.aspx?proj=47571 as ChiCTR2000028778.

Cognitive-Behavioral Therapy for Insomnia (CBT-I) is the gold-standard treatment for insomnia, which is common among breast cancer survivors (BCS). This pilot randomized controlled trial tested the first CBT-I intervention for Spanish-speaking BCS delivered using eHealth. Participants (N = 30) were Spanish-speaking BCS with insomnia symptoms recruited in Puerto Rico and randomized to a 6-week eHealth CBT-I group intervention or a waitlist control. Primary outcomes were acceptability (recruitment, treatment satisfaction) and feasibility (retention, attendance). Secondary outcomes were group differences in sleep outcomes post-treatment (i.e., insomnia symptoms, sleep disturbance, sleep efficiency). Recruitment (95%) and retention (97%) were excellent. All CBT-I participants (100%) attended ≥ 3 of 6 sessions. Satisfaction with CBT-I was acceptable. Post-intervention, there were medium to large group differences for average insomnia symptoms (d = 1.02), sleep disturbance (d = 1.25), and sleep efficiency (d = 0.77) favoring CBT-I. There were small/medium to medium/large group differences for the proportion of participants with clinically significant insomnia symptoms (d = 0.52), sleep disturbance (d = 0.67), and low sleep efficiency (d = 0.33) favoring CBT-I. Spanish-language eHealth CBT-I for BCS was acceptable and feasible and showed preliminary efficacy. ClinicalTrials.gov TRN: NCT04101526 (Posted September 24, 2019). [ABSTRACT FROM AUTHOR]
